To all whom t may concern j Be 1t knownA that I, R101-mno MURRAY, a

citizen of the'United States, and residing at New York, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Building Blocks or Slabs, of which the following is aspecification, such as will enable those skilled in the art to whichitappertains to make and use the same. y

This invention relates to blocks or slabs preferably composed ofkcement, concrete or similar material and which are adapted to be used inthe construction of the walls of buildings and roofs of buildings, andthe object of the invention is to provide a block or Vslab of the classand for the purpose specified which is provided with one or morehook-shaped 'spring attaching devices by means of which the block orslab may be con* nected with and suspended from 'a suitable support; afurther object being to provide means for reinforcing the block or slab,and with these and other objects in view `the invention consists in abuilding block or slab which is simple in construction and eliicient inuse and which is constructed as hereinafter described and claimed.V

The invention is fully disclosed in the following specication, of whichthe accompanying drawing forms a part, in which the separate parts of myimprovement are designated` byy suitable reference characters in each ofthe Views, and in which Figure 1 is an outside view of a part of thewall of aibuilding which involves my improved blocks or slabs, partV ofthe construction beingbroken away and in section;

Fig. 2 a partial transverse section on the line 2-2 of Fig. 1; n

Fig. 3 a sideand sectional view of one of my improved blocks or slabswhich is used inthe construction of the wall as shown in Figs. 1 and 2;

Fig. et a view similar to Fig. 3 of a modilied form of the block orslab;

Fig. 5 a diagrammatic'transverse sectional view of a part of a roofshowing the same constructed with the blocks or slabs shown in Fig. 4;and, Y

Fig. 6 a side edge view of two different forms of blocks or slabs whichI may employ i in the construction of a building.

In Figs. 1 and 2, I have indicated for illustrative purposes, a part ofthe foundation 10 of a building, rat "l1 the upright frame members and,in the practice of my invention, I secure to the members 1 1 kaplurality of longitudinal and spaced strips 12 withV which my improvedbuilding blocks or slabs A13 are connected.L j

In Fig. 3 of the drawing I have shown in detail one of the blocks orslabs 18 which is approximately rectangular in form, and one side wallthereof is provided with a tongue 14 while the other side wall isprovided with a groove 15 adapted to receive the tongue 14 of anadjacent block or slab in the construction of a wall. The lowerfaceofthe block or slab 13 is provided with a tongue 16whilc the upperface thereof is provided with a groove 17 adapted to receive the tongue16 of the yblock or slab placed thereon.

Embedded in the block or slab 13 is a rectangular rod-like reinforcingframe 18,' which is embedded in the block or slab approximatelycentrally thereof as is illustrated in F igj2 of the drawing, and theside and ends of the frame 18 are connected by a wire mesh or otheropenworli construction 19, which adds to the reinforcing qualities ofthefraine 18. The central portion of the frame 18 of the top member 20thereof is bent downwardly and outwardly through one face of 'the blockor slab 13 as, shownat 21 in Fig. 2, and that part of the framey whichprotrudes through the inner face of the block or slab is bent downwardlyinto a' yoke-shaped spring'hook device 22 having a shoulder portion 23,which is adapted to pass beneath the strips 12 of the framework of abuilding to securely hold and lock the blocks or slabs 13 in position. Y

It will be apparent that, in the construction of a wall of a building,the blocks or slabs 13 are placed one upon another and one beside theother in which operation the tongues 14T- 16 pass into the grooves 15-17respectively in the adjacent blocks or slabs in the manner illustratedin Figs. 1 and 2 of the drawing, and in this operation theyokeshaped'spring hook devices 22 onk eac-h of the blocks or slabs ispassed over the spaced strips 12 in the manner illustrated in Fig. 2. Itwill be understood that I am not neces-` sarily limited to the use ofone spring hook device 22 on each block as any number of these devicesmay be employed depending largely on the size of the block or slab and asuitable reinforcement will be provided to suit the size and generalstructure of the block slab., and, of course. these blocks or slabs maybe used as 'facings in which event they will be made comparatively thinand, in other instances, the walls may. be. conf,

structed of the blocks or slabs "13 only, in or slabs willbe n'iade bposed of comparatively thin cement, concrete or similar substancereinforced by wire mesh, or other openwork material 29 and embedded inthe block or slab 28 is ay wire frame, 8O one side of which is bent toform two yoke-shaped spring. hooi;l devices Sylwhich extend through oneacefot'. the blockL or slab 28, and saidtramel 30 is also bent-to formtwo spring catch devices, 32 which are preferably in line with thespring hook devices 31.

.The hook devices 3l are of the saine general` forni and construction asthe hook devices 22 shown in Fig.` 2 of the drawing, and in the use ofthe blocks or `slabs28 in constructing,` the roof of a building, theyokeshaped spring hook devices 31 arelpassed over,` the strips 25 tolock the blocks or, slabs in connection therewith, and these blocks orslabsare overlapped in the usual manner andas indicated at 33 in Fig. 5ot the drawling,land the spring catch devices 32 ofi one slab passesover and engages the upper end4 iortion of the block or slabtherebeneatli.

Ihe first or lower tier of blocks 0r slabs 28 indicated at 34 in Fig. 5`of the drawing, or the freeedges thereof, are reinforced and held inposition by a strip 35 secured to the framework 2li oif the roof andover whichv the spring catch devices 3 2 ot the lower tier' otblocks orslabs28V pass.

In the constructions shownin ligs.v 1 to- 5 inclusive, the blocks orslabs are shown square or rectangular in foi'nibut, of course, myinvention is not limited to this extent as the blocks or slabs may bemade of, any desired shape or form, and` in Fig, 6 Ihave shown at 36 aV-shaped block or slab for use' in corner` construction and at 37 insaid tigiire I have shown an arc-shaped block or slab used in theconstruction of columns, rounded corners, etc. i Y

My invent-ion is not necessarily limited to any specific use oftheblocks or slabs, or

to that use herein illustrated, nor am I necessarily limited to anyspeciiic iorni ot rein forcement inrsa'id .blocks or slabs, thedistinctive feature of the invention being the provision otthe springhook-shaped devices vhich not only serve to support the blocks orslabsbut lock said blocks or slabs against inward, outward or upwardmovements, as well as serving to aid the supporting of the separateblocks or slabs, and said blocks oi' slabs may be overlapped orinterlocked in any desired manner to form 'a neatand 'fin-l ishedwallo;` root construction, and various changes `in and mod ications ofthe construction hereinushownV and described, may

be. made, within the scope of the appended claiins, without departingfrom the spirit lot my invention or sacrificing its advantages,

Having fully describedmy,l invention, `what I claim` as new; and, desireto secureby Lettersljatent, isi- 1. A block or slab of cementitiousnaar.

In ltestimony that I claim the foregoing as my invention I have signedmy naine in presence ofthe subscribing witnesses this 8th day of March,1920.
